Italian 1860 Corvette.

 Caracciolo was a screw corvette of the Italian Regia Marina (Royal Navy) built in the 1860s. She was the first vessel of that type built after the unification of Italy, though the Italian fleet inherited several screw corvettes from the navies of Naples, Tuscany, and Sardinia. The ship was armed with a main battery of six 160 mm (6.3 in) guns. Originally built with both steam and sail propulsion, Caracciolo later had her engine removed for use as a training ship.
